This mini lesson helps students visualize how the Hydrosphere and Cryosphere interact to produce changes in land and sea ice. 

This activity invites students to simulate and observe the different effects on sea level from melting sea-ice.

Arctic sea ice is the cap of frozen seawater blanketing most of the Arctic Ocean and neighboring seas in wintertime. It follows seasonal patterns of thickening and melting. Students view how the quantity has changed from 1979 through 2018. 

Students watch the video Frozen Earth and answer the following questions that discuss how ice helps moderate the planet's temperature using NASA satellites.

Students explore positive feedback effects of changing albedo from melting Arctic sea ice.

Students develop and test a hypothesis about how albedo affects temperature.
